SH2-282
Sh2-282 is an emission nebula in the constellation Monoceros.
It is observed in the north-central part of the constellation, about 3° south of the Rosetta Nebula; it can be photographed with some difficulty through an amateur telescope of high power equipped with special filters and long exposures are required. Being only 1.5° north declination, it can be observed from all populated areas of the Earth with ease; the most propitious period for his observation in the evening sky runs from December to April.
It is an H II region extended for about 50 light years, within which several cometarian structures are known, indicating the presence of eroded phenomena caused by the stellar wind of the nearest spectral class O and B stars, and in particular HD 47432, a pulsating variable blue giant visible on the northeast side of the nebula; this star has an average magnitude of 6.21 and is located at a distance of 1250 parsecs (4075 light years). The cloud is located in the same galactic environment as the Monoceros OB2 association, bound to the Rosetta Nebula and located on the inner edge of the Perseus Arm, and which would also include the star HD 47432; NGC 2282, a reflection nebula a little further east, also belongs to the nebula system.
